Interpretation: Well we've been given one and ya it works, but I like to be difficult so I'll add one or two more on top of it anyway.
First, the old saying "the heat of the moment" comes to mind, combined with the title "I listened to the heat" and of course the connotations of heat, be it lust, anger, and so on. With that in mind...
Obviously, the girl is not satisfied, but I'll go so far to say as that doesn't preclude the existence of a sexual orgasm. Indeed I think to put it up a notch, the orgasm happens but the expectations do not.
Love IS divorced from sensation, while one may pull and call out for the other, they are of separate energies in the universe.
So in this really odd construct I am building (bear with me) the deadline is the approach of an orgasm that does occur. And the person is hoping that their heart is uplifted with it, but while the pull is there it is but illusory, sex does not build up love (and sometimes it is or should be that the reverse is similarly true).
So there is level two, it is about an orgasm being seen as a key to something more.
Now level three, making it physical again, on top of level two. While one person in this tryst is having an orgasm and feeling it, they are watching the other and want to see the same for them. They are not looking for it to 'ratify' their love, but are simply in the business to 'satisfy' their love, they are only at it because love dragged them there. They hope love will bring the physical sensation in this case, even if they are incapable. (so lets call this the level of impotence)
Level four, and here I'll call it the summit, they both have an orgasm, but one is dwelling on being able to detect it in the other. They want that person to express it, to yell it out, just so they can know the love is also not silent. And that other person doesn't, and it is taken as a sign. (climb this tree higher, both are doing this, but I'll refrain from an infinite loop here)
So feedback: Tried though depressed is great, but I like it without the I. Because then the more devilish of us can assume its not just one person trying because they were depressed.
I'll be a mechanics nazi for once, you have tick to tock, shout to whisper, I think you should make the second line go from tock to something. The perverted side of course has its suggestions I'll refrain from.
To just hear the sound of silence cry
It made me realize that love is cold
Reason I think, despite the last stanza being about temperature, that you should use the word 'dry'. Inserts an entire other set of imagery into it with one word, even though it may seem inconsistent. However, it goes from hot to silent as well, which links sound mentioned earlier, the dry/cry rhyme creates a linkage, and really dry goes with warm and hot as well (again I'm walking the lines of G-rated I know).
This one is a mind stir. At first I wasn't "feeling" it, but the end made me go back and read it again. I really love synesthesis(mixing of the senses). I love the word itself, and I love the use of it. You have an interesting progression, but I'm not sure the thoughts connect well enough. The more I read, the more I like it. I'd like to know what the deadline is. I think I know where you're going in the second stanza, but I'm not sure. Maybe you could explain to me. I enjoyed reading
